msvc: disable compiler warnings when building all Externals (cl /W0), except for wxWidgets, where all warnings are fixed.

Note warnings may still be generated by code in Externals if it is included into warning-enabled code (this is the case for libusb).
Also, quiet an intellisense warning in wxWidgets caused by using __w64 for an inapplicable type.
